' or ice compartments by crossed partitions giving a grid-like orchecker-board appearance to thepans when viewed from, above. Sleeves, constituting the walls of pockets for receiving the ice trays are generally formed in the brine tank (when brine tanks are used) within which the expansion coil of the expansion' or refrigerating ele'ment, (or boileriffas 'it is sometimes designated) is inclosed. Usually the sleeves or tubular bodies referred to are surrounded by the ,turns of the expansion coil immersed in the brine. Or if a brine tank is omitted, the sleeves or pockets for the'ice trays are still disposed. wlthin the turns of the expansion coil `but not in contact with brine. And in the latter case these sleeves or pockets may extend from a cover plate or anel attached or lyingclose to-that side o the coil that faces the front of the cabinet.

In operation water is apt to condense on thefront of the brine tank, or the front late of the refrigerating coil, and runs downward thereon. Itis one of the objects of this invention to prevent this condense water from entering the ice pans, since it lmay contaminate the ice, or overiow andfreeze the anto the sleeve. A Incase t e ice pan freezes to the sleeve by reason of the'cells having received s'o muchwater that it overflows when congela? .tion begins, orif for any other.. rea son is formed 'within'the sleeve inA such position` las Yto obstruct the withdrawal-'of the ice tray, breakage of. the tray handlecpnnec tions to the panA is apt to occur .whenan` .attempt is made towithdraw the "traglin" V )ectu of this inventionis to enable broken .conf-X order tolharvest the ice. lnothe'rgo nectionsoccnrringfas described to be readily re aired.

In Fig. 1 the back of the outer shell or casing of a refrigerating cabinet is lindiof said shell or casing by 11, the front by 12, and the door of the a at refrigerating compartment by 13. The front l frame structure is shownat 14; 15 indicates cork board insulation cemented tothe sheet metal lining l16 of the compartment and spaced from the casini to form an air space ar, (of lwhich there are in practice two) supported by the upper cross member of front frame Hand a cross cleat 1'9 on the casing back. .Said channel bars sustain the bolts 20 which extend downward through holes in the web of the chane nel and are suspended by their heads said web. These bolts penetrate the cork insulation and the compartment lining; their lower threaded ends are passed through ears 21 on metallicstrapsor stirrups 22, which are suspended by nuts 23 on the ends 'of the bolts below said ears, -while spacing sleeves 24"on the bolts between the stlrrups and theceiling of the compartment revent .any .upward movement. The suspenf ed stii-,

wall of ,the brine tank is indicated at 26. Extendin inward and rearward from the front' w l,are sleeves orxtubular bodies 27 forming pockets 28 for the ice trays. These pockets'have o en front 4ende and .are'sur- Ice trays havint; relativel shallow pan 29 fit loosely wi pocets 28.v The P11112? are divided into. a number 0f i035 com:

numeral v25. Within the brine' tank, it will be understood, the usual expansion coil is inclosed. The front v partments 30 b the grid-like intersecting artitions 31. paced from the front of the rine tank between it andthe door 13, is a front plate 32 that prevents access to the interior of the refrigerating compartment except to enable the ice trays to be inserted and removed. The front plate may be of metal coated witha porcelain or vitreous enamel, and suitably embossed as at 33 that part that is opposite the open ends of the pockets .28. Ii1`the embossed part 33 are oriic 34 registering with the open ends of pockets 28 and sufticiently large to permit the trays 29 to be passed through them into the pockets 28, or withdrawn froml said pockets through the openings.

Soldered or welded to, the front end of each ice pan are two bosses 35, which are thus secured to the pan in such manner that no obstruction is present on the inside to interfere with removal of ice. Thev bosses 35 are preferably of metal and may be of spool-like formation having their inner lianged ends secured to the tray by a mass of soldering or welding metal as indicated at 36. Both bosses are drilled and countersunk and the drilled holes threaded as at 37. A Ilan ed tubular anchor bolt 38 with a slotted hea seated in the countersink is threaded into the threaded hole in each boss and a slender, flatheaded machine screw 38a iS threaded into the center of eachanchor bolt. The screws 38a pass through countersunk holes in the flanges 39 of a looped handle 40, through a stop and cover plate 41 and through a' separate spacer block 42, preferably of heat insulating material such as wood, inserted between the metallic stop and cover plate 41 and the metallic boss 35. The stop and cover plate 41 is preferably dished, as shown, and' its flange bears upon the front 33 when the tray is pushed into the sleeve. It is of a size and shape to cover the opening 34, preferably has the appearance of a 2drawer or tray front and serves not only to close the opening but also as a stop and gauge -to determine the position of the ice pan with respect to the pocket.

It will be observed that in thedrawings the front end of the pan does rnot extend beyond, nor flush wi-th the front 26 of the brine tank, but occupies a position well within the pocket 28. In-the position shown condense water or water formed by melting frost that may gather on -the front of the brine tank will not run into the ice pan, but will drip across the space in front thereof. The bosses 35 and spacing blocks 42 are of 'uch length as to space the front of the ice pan from the stopfplate 41 such a .distancevthat whenfthe stop plate engages the front 33, the ice pan willbe entirely within the pocket. InAbuildin refrigerator cabinets and installing there rigerating unit it is likely to happen that the space between the front plate 33 and the front of the brine tank will not always be the same in each of several piecesof apparatus. vBy spacing` saidA stop plates 41 from the front of the ice trays a distance greater than the distance between the front -plate 33 and the front 26 of the brine tank that is likely to exist in any refrigerator, the result will be that the front end ofthe ice pans will always be well within the `pockets 28, in any rinstallationvof one type when the stop plate 41 is pushed against the front plate 33.` Thus, by no untoward accident in the course of manufacture will any refrigerating apparatus of the-same type have the ice pan in position to receive the drip of condense water or frost onlthe front of the brine tank when the handle is pushed 1n.

Although in Fig. 1 the invention is illustratedv as applied to a refrigerating unit equipped with a brine tank, it will be obvious that it is also applicable to such a unit where the expanding coil is open, or not immersed in brine. The numeral 26 in Fig. 2 may be assumed to indi`1 cate a cover plate in' the latter type of unit instead of the front wall of a brine tank, and the sleeve or tubular member 27 as extending rearward within the turns of the ex pansion coil.

In operation the cells or compartments 30 of the ice pan will be charged with water and the tray pushed into place with Jthe pan seated' within pocket 28. After the water has frozen, the tray may be withdrawn and the ice or so much as may be required removed from the pan. yShould the tray be frozen 'to the walls of the pocket by reason of overflow of water from the pan or the freezing of water of condensa-y tion within the front opening ofthe pocket,

'it is possible that the bolts or screws 38,

When the tray has been pushed into the pocket 28 until the flange of stop p1ate-41 engages the front 33, the front of the pan will be well within the pocket so that condense water that may run down the front .ofthe brine tank (or cover plate as the housed case may be) will not enter the pan to contaminate the ice or overflow andl freeze 'it to`the sleeve. Y

Although I have described and shown' a 3.5 tance between the) front plate engaging frigerating unit, a pocket-forming sleeve preferred embodiment of my invention, it will be apparent that modications thereof may be made within the definition of the appended claims without departing from the principles of the invention.
